IMPROVEMENT IN MACHINES FOR VARNISHING 0R COLOR-ING LEAD-PENClLS, Sac.

Specification forming part of Letters Patent No. 125,362, dated April 2, 1872.

To all whom it may concern.-

Be it known that I, EDWARD WEIssENBoEN, of Hudson City, in the county of Hudson and State of New Jersey, have invented a new and Improved Machine for Varnishing or Coloring Lead-Pencils and other articles by dipping; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanyingdrawp ing which forms part of this specification, and

Figure l' represents a sectional elevation of a machine for this purpose constructed according to my invention, and Fig. 2 represents an elevation view at right angles to Fig. 1.

Similar letters of reference indicate corresponding parts in both iigures.

The principal object of this invention is the uniform raising of wood-incased lead and other pencils, or other similar articles, from the bath of varnishing or coloring material, after having been dipped therein, at degrees of velocity corresponding with the nature and consistency 0f the said varnishing or coloring material and the thickness of the coat that is desired to be left thereon; and to this end the invention consists in a dipping-machine wherein the dipping apparatus is connected with and,`

operated by a train of gearing driven by a weight or its equivalent, and having an adjustable iiy, whereby the desired end is atta-ined. It also consists in a novel arrangement in connection therewith of the winding-cord relatively to the winding-shaft, whereby the winding up of' the weight or spring allows of the simultaneous lowering of the dipping-frame or holding-bars-and the pencils or other articles suspended thereto by their own weight.

Referring to the accompanying drawing, A represents the bath for containing the varnishing or coloring material, and over which the pencils or other like articles to be coated are suspended in the usual way by holding-bars B. These holding-bars B, though not confined to any particular form or construction, are prei'- erab] y of such as are represented in the drawing, and which, being a subject of' another patent now applied for by me, a further description of them here is deemed unnecessary. The holding-bars B are bolted together, as shown, having separating washers between them for the purpose of holding them, and consequently the pencils or other articles separate from each other while being dipped When thus bolted together they, collectively, constitute what I term a dipping-frame, and are supported upon a carrier, C. This carrier C may be of the form here represented or of other suitable form, and arranged to slide between vertical ways D D of the frame F, so that the descending or ascending movement of the same will cause the lowering or raising oi' the pencils or other articles into or ont of the coating material contained in the bath. Attached to this carrier (l are cords a a, which, passing upward, connect with pulleys b b carried upon a horizontal shaft or windlass, E, arranged at or near the top of the frame. G is a gearingwheel suitably arranged at or near the upper central portion of the frame, and so connected with the carrier C by means of a cord passing from the spindle to the windlass E, and so acted upon by a weight or spring attachment that, when wound up, will, by running down, cause the raising of the said carrier. This gearingwheel G gears with the pinion of a similar gearing-wheel, G', which, in turn, gears with the pinion of a fly, I, the wings or fans of which, being so pivoted upon their radial arms t' as that, by being turned thereon, may be made to meet with greater or less resistance from the air during the rotation ot' the said fly, thereby regulating the speed oi' the gearing-wheel G and its spindle, and thus provide for the raising of the pencils or other articles from the dippin g-bath at different degrees of velocity. By this means pencils, 85o., by being slowly raised out of the dipping-bath, are allowed more time to drain, and consequently come out with a thinner coating on them than if they were raised more rapidly; and, owing, also, to the variation in the consistency of the different coloring and varnishing materials used, some require longer time to drain oft its accumulated snrplus from the surfaces of the pencils or other articles than others, and therefore should be a more slowly raised. The cord o, which is attached to a central pulley, b', of the windla-ss E, is made to pass around a spindle ofthe gearin g-wheel Gr a suitable number of times to allow, by its subsequent unwinding, the lowering ofthe dipping-frame and the complete submersion of the pencils in the dipping-bath. It is then, after being secured by passing through a transverse hole in the said spindle, which also serves as the winding-shaft, passed downward, and a weight, H, attached to its pendent extremity, so that the turning of the spindle necessary to the winding up ofthe weight will, by unwinding the surplus cord previously wound thereon, allow of the lowering of the carrier and its contents by gravitation.

What I claim as my invention, and desire to have secured by Letters Patent, is-

1. The dipping-machine for pencils and other articles, having its dippingframc connected With, and operated by, a train of gearing driven by a weight or its equivalent, and having an adjustable iiy, substantially as and for the purpose herein set forth.

2. The arrangement of the winding-cord c relatively to the windingshaft, whereby the winding up of the weight allows of the simultaneous descent of the holdin g-bars or dippingframe by gravitation, substantially as herein described.
